s Tuo on BUTTON.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom it may concern:

Be it known that I, IRVING M. SYLvEsTER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Studs or Buttons, of which the following is a specification.

This invention has reference to an improvement in studs or buttons, and more particularly to an improvement in pipe-stem studs used generally in shirt bosoms.

The object of my invention is to improve the construction of a pipe-stem stud, there by simplifying and strengthening the construction and reducing the cost of manufacturing the stud.

My invention consists in the peculiar and novel construction of a pipe-stem stud having a head, a hollow L-shaped shank forming integral the tubular stem and shoe of the stud, a sliding looking-bar having annular grooves in the shoe, and means formed integral with the shoe adapted to engage with the grooves in the locking-bar to hold the locking-bar in either the closed or extended position, with details of construction, as will be more fully set forth hereinafter.

Figure 1 is a face view of my improved stud, showing the locking-bar in the extended position. Fig. 2 isa view looking at the side of the stud with the locking-bar in the extended position. Fig. 3 is an enlarged sectional view taken on line X X of Fig. 2, showing the spring-snap formed integral with the shoe of the stud. Fig. 4 is an enlarged sectional view taken lengthwise through the stud, showing the spring-snap engaging with a groove in the locking-bar to hold the same in the extended position; and Fig. 5 is an enlarged cross-sectional view taken on line Y Y of Fig. 3 through the shoe, spring-snap, and locking-bar of the stud.

In the drawings, 0 indicates the head, I) the L-shaped shank forming integral the tubular stem 0, the tubular shoe (1, and the spring-snap e, and f the sliding locking-bar, of my improved stud.

The head a may be of any material or configuration and secured to the stem 0 in any well-known way. In the drawings the head a, is shown as a semispherical shell a, secured to the disk 0. by spinning the edge of the shell over the edge of the disk, which in turn is secured to the open end of the stem 0 by solder. A

The shank b is constructed of hollow springwire bent L shape to form a tubular stem 0 and tubular shoe (1, as shown in Fig. 4. A hole I) is formed in the bend of the shank b for the locking-barf, which is held in the tubular shoe (1 and extends through the hole I) when the bar is in the extended position. The snap 6 has the inwardly-extending transverse rib e, adapted to enter a groove in the locking-bar and hold the same in either the closed or extended position. The snap e is formed integral with the tubular shoe (1 by cutting the two longitudinal parallel closelyassociated slits b I) through the shoe, as shown in Fig. 3, and then stamping in the central transverse rib e on the spring-strip formed. by the slits 6 W, as shown in Figs. 4 and 5.

The sliding locking-bar f is constructed from a round bar to have the annular grooves f and f, the slightly-enlarged end f and the usual pointed end f 4 to facilitate the entering of the shoe d and stem 0 of the stud in the stud or button hole of a shirt-bosom.

In the use of my improved stud the locking-barf is pushed through the shoe d into the closed position by pushing on the end f of the bar. This brings the rib e on the spring-snap 6 into the groove f in the locking-bar, firmly holding the same in the closed position under spring tension. The pointed end f the shoe d, and the stem 0 are now pushed through the stud-hole in the shirtbosom. The locking-bar f is then pushed into its extended or locked position on the back of the shirt-bosom by pushing on the end f and held in this position by the rib e on the spring-snap e enteringthe groove 1' in the lookingbar, as shown in Fig. 4, thus securely locking the stud to the shirt-bosom.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a pipe-stem stud, a head, a hollow L- shaped shank forming a tubular stem and shoe, a locking-bar formed with annular grooves extending in said shoe, said shoe being formed with a pair of longitudinal parallel closely-associated slits intermediate its length, which slits extend to points adjacent In testimony whereof I have signed my the ends of said shoe, the material between name to this specification in the presence of said slits forming a snap supported by each i two subscribing Witnesses.
